Promotional tokens made of Arboform. Arboform (from Latin: arbor meaning tree) is a trade name for a bioplastic composed of three natural components: lignin, cellulose fibers and some additives. As a thermoplastic, it can be molded and is therefore also called 'liquid wood'.
Packaging peanuts made from bioplastics (thermoplastic starch) Thermoplastic starch represents the most widely used bioplastic, constituting about 50 percent of the bioplastics market. [25] Simple starch bioplastic film can be made at home by gelatinizing starch and solution casting. [26]
Wood-plastic composite. Wood–plastic composites (WPCs) are composite materials made of wood fiber/wood flour and thermoplastic(s) such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polylactic acid (PLA). In addition to wood fiber and plastic, WPCs can also contain other ligno-cellulosic and/or inorganic filler materials.
There is also much debate about the total carbon, fossil fuel and water usage in manufacturing biodegradable bioplastics from natural materials and whether they are a negative impact to human food supply. To make 1 kg (2.2 lb) of polylactic acid, the most common commercially available compostable plastic, 2.65 kg (5.8 lb) of corn is required. [57]
The straw fibers could be found in many parts of the world, and it is an example of a low-cost reinforcement for biocomposites. The wood fibers could be recycled or non-recycled. Thus, many polymers as polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC) are being used in wood composites industries.
Whether a material is biodegradable is determined by its chemical structure, not the origin of the material from which it is made. [14] Indeed, the sustainability benefits of drop-in biobased plastics occur at the beginning of the material life cycle, but still, when manufactured, their structure is identical to their fossil-based counterparts ...

made from wood pulp, a renewable resource; can be composted or incinerated; can be dyed, however special dyes and pigments are required since acetate does not accept dyes ordinarily used for cotton and rayon (this also allows cross-dyeing) resistant to mold and mildew; easily weakened by strong alkaline solutions and strong oxidizing agents
